1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A client is being assisted to lie in the Sims' position. In what position does the nurse arrange the client?

• A. The client lies on his side with the upper leg flexed
• B. The client lies on his back with his head lower than his feet
• C. The client lies on his abdomen with a pillow supporting his head
• D. The client is sitting up at a 90-degree angle

Correct answer: A

Rationale: The Sims' position is a side-lying position used for examinations or comfort. In the Sims' position, the client lies on their side with the upper leg flexed. The abdomen is slightly downward, and the lower arm is positioned behind the body. A pillow can be used to support the leg. Choice B is incorrect as it describes a position with the client lying on their back with the head lower than the feet. Choice C is incorrect as it describes a prone position, not the Sims' position. Choice D is incorrect as it describes a sitting position, not the Sims' position.

3. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?

• A. Controls stray electrical currents.
• B. Promotes efficient use of electricity.
• C. Shuts off the appliance if there is an electrical surge.
• D. Divides the electricity among the appliances in the room.

Correct answer: A

Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.

4. Which type of shock is related to low blood volume?

• A. Psychogenic
• B. Cardiogenic
• C. Anaphylactic
• D. Hemorrhagic

Correct answer: D

Rationale: Hemorrhagic shock, also known as hypovolemic shock, is directly related to low blood volume due to significant blood loss. In hemorrhagic shock, the body's circulating blood volume is reduced, leading to inadequate perfusion of tissues and organs. Psychogenic shock is caused by emotional distress, not blood volume changes. Cardiogenic shock results from heart failure, not low blood volume. Anaphylactic shock is due to a severe allergic reaction, not a reduction in blood volume.

5. You are preparing to admit a patient with a seizure disorder. Which of the following actions can you delegate to an LPN/LVN?

• A. Complete admission assessment.
• B. Set up oxygen and suction equipment.
• C. Place a padded tongue blade at the bedside.
• D. Pad the side rails before the patient arrives.

Correct answer: B

Rationale: The correct answer is to delegate the task of setting up oxygen and suction equipment to the LPN/LVN. This task falls within their scope of practice and can be safely performed by them. Completing the admission assessment (Choice A) typically requires a higher level of assessment and critical thinking, making it more appropriate for a registered nurse. Placing a padded tongue blade at the bedside (Choice C) involves potential airway management, which is a more complex task and should be done by a higher-level provider. Padding the side rails before the patient arrives (Choice D) is a task related to patient safety and should be done by the healthcare team as a whole, not solely delegated to an LPN/LVN.
